We used 2 other SQL engineers prior to meeting Shafir and also attempted a repair using a database repair application which also failed. We were at a point where nothing was working and we were coming to the conclusion that this was not repairable as there were too many errors. Shafir was very confident that he could repair the database and after watching him work for just a few minutes I immediately felt some hope of a successful repair. After working on the database for several hours Shafir managed to repair the database and get it working better than it was before. Working 20 years in IT I had never seen anything like it. Shafir is very professional and truly an SQL expert. I would highly recommend Shafir for any SQL project. Thank you." - Dean Cutajar, Director - Access IT ⭐⭐⭐⭐⭐ "Amazing experience! Shafir did the impossible. He was able to take a highly corrupted database and bring it back to life with zero data loss. Once repaired, he optimized the database and has it running better than it was before the corruption. He is responsive and easy to work with. Highly recommended. Will use again in the future."
